For the WTC tubes, I understand Lexan is the best choice, yes? I am getting to the part about ordering tubing for two boats , in 4 inch diameter. So I go to McMaster Carr website to look at what they have. They list polycarbonate tubing "similar to" Lexan. I seem to remember one composition(maybe acrylic?), Looks the same, but is more brittle, and cracks and develops "spider webbing". I just want to be certain, before I order for two boats. Feedback from the experianced please.

I have had good luck buying remnants from this online company.They can source remnants from their multiple locations.The best way to inquire is to call them.Better prices than McMhttp://www.professionalplastics.com/

Thanks for the tip.I need to stuff two Engel 750 or 825's in the Borei. I have not measured yet, because I am still putting the ends on, But I know I need a min of 40 inches for that one. The X-tail will be here monday. It gets the 500 ML Engel I already bought. I need to measure them both, to see what I need, but it is coming soon. I am still gathering "stuff" right now, but getting there. Paul, do you remember where Gail got the stainless threaded rod and carbon fiber tubes he sleeved them with?
